Funny thing about art is that depending on who looks at it they see different things. Color and being creative are what drive me. Art is not always real. I always say that if you want something that looks real then take a photo. It gets no more real than a photograph. If you want something that is way cool then it has to be art. With art the imagination takes over and you see what you see. It could be the sky or it could be the ocean. Does not matter. If you like it, then its art. So red tree or a green sky is just fine. Enjoy.
